Morning Guys
Over the past few days I've been troubleshooting a circuit, looking for a fault, which involved a great many checks for signal and voltage at different points, using a DMM and my 'scope. I've noticed a significant discrepancy between the voltage reading of my DMM and the 'scope.
I have 3 handheld DMM's none of which would be described as a quality instrument, but the 'scope is fairly new and reasonable quality.. .. .. I don't yet possess a quality bench DMM, but it is on my christmas list
I have seen a number of small circuits which include a reference voltage chip, designed to give an accurate output voltage at 10 vdc for calibration purposes .. my question ?? ... .. .. are they any good ? Do they work ? Are they accurate ?
In case I don't get another chance, I would like to wish all participants in ETO, whether Administrators; MOD's; Very Helpful Members; Helpful Members; Active Members; Members; Guests and anybody else who isn't in that list a very Happy Christmas & New Year.
There is an absolutely huge Thank You for all the help, advice and patience you have given me in this my first year as an electronics hobbyist. I have learnt such a lot from you all, not least, how much there is to learn. I have a great deal of respect ... .. .. .
